Click a heading to sort. Hover over a heading for help.
Class of the river gives an approximate difficulty. See the safety section of this website for more
information on rapids and ratings.
Level gives the most updated gauge tied to a river. See the notes and comments for how to
interpret the reading. Readings may be delayed, come from bad sources, or have other miscalculations.
Additional detail on a gauge can be ascertained by a simple click to the level. Metrics for a given level are:
CFS, Stage (ft), in/hr for rain, and r.c. meaning no direct flow, but 0.0-1.0 is boatable.
The astrix (*) indicates a comment on the flow, plus (+) indicates a good flow,
tilde (~) indicates that this is a stand-in for the real flow, or the flow is delayed, an explination mark (!)
indicates there is a warning associated with the flow.
Relative Level explains how low or high a reach is based on being above or below the
recommended range. This column is used when color is not visible or obvious (mobile phones, or color blind people).
The first letter is L,R, or H for Low, Runnable and High. The second number is 0-9 where 0 is bottom end
and 9 is top end. Therefore, "R0" is low, "R5" is medium, "R9" is upper high.
If you see a river that is "H0" and coming down, maybe it will run tomorrow. Sort the list
by r.c. to find rivers that are in the ideal range in your area.
Trend gives information on how quickly a level is rising or dropping using r1-r2/(t1-t2) using the last readings gathered.
Readings may be spaced hours apart and may miss local spikes. Be careful when using these.
